Angular Tables

Introduction

Understanding how to work with tables in Angular is crucial for any web developer. Angular, a popular JavaScript framework, offers a range of features to manage data in tables effectively. In this article, we will cover everything from basic table implementations to more advanced features like sorting, pagination, and searching. This guide is tailored for beginners, ensuring an easy learning curve.

AngularJS Tables

Tables are a fundamental part of data representation in any web application. AngularJS makes it simple to create and manipulate tables to display data dynamically. To get started, we will create a basic table example.

Table Example

Using AngularJS with Tables

In AngularJS, you can bind data to the table using the ng-repeat directive. This directive allows you to iterate through a collection of data and create a table dynamically.

  

    

      
{{ person.name }}
      
{{ person.age }}
      
{{ person.city }}
    
  


    

ng-repeat Directive

The ng-repeat directive is essential in AngularJS for displaying lists of data in a table. It creates a new scope for each item in the collection and gives you access to individual properties.

How ng-repeat Works

By using ng-repeat, you can easily create rows for each entry in an array. Here’s a simple example:

  

    

      {{ x }}
    
  


    

ng-repeat with Objects

You can also use ng-repeat with objects. Here is an example:

  

    

      
{{ key }}
      
{{ value }}
    
  


    

Sorting Tables

Sorting tables is an important functionality that enhances data visibility. AngularJS provides the orderBy filter to sort data easily.

Sorting Example

Here is a basic example of how to sort a table:

  

    

      
Name
      
Age
      
City
    
    

      
{{ person.name }}
      
{{ person.age }}
      
{{ person.city }}
    
  


    

Using OrderBy Filter

The orderBy filter can be applied directly in the ng-repeat expression to sort data based on a specific property. The example above demonstrates this usage.

Pagination

Pagination is essential for displaying large sets of data in a manageable way. AngularJS allows you to implement pagination seamlessly.

Pagination Example

Below is an example that demonstrates pagination:

  

    

      
{{ person.name }}
      
{{ person.age }}
      
{{ person.city }}
    
  
  
  Previous
  Next


    

Implementing Pagination in Angular

To implement pagination, you can create a simple pagination mechanism using currentPage and pageSize.

angular.module('myApp', []).controller('myCtrl', function($scope) {
  $scope.people = [
    {name: "John Doe", age: 25, city: "New York"},
    {name: "Jane Smith", age: 30, city: "Los Angeles"},
    {name: "Mike Johnson", age: 35, city: "Chicago"},
    // More data...
  ];

  $scope.currentPage = 0;
  $scope.pageSize = 3;
});

    

Searching with Input

Integrating a search feature is vital for improving user experience. You can easily create a search input field connected to your table data.

Search Example

This example demonstrates how to implement a basic search feature:

  
  
  

    

      
{{ person.name }}
      
{{ person.age }}
      
{{ person.city }}
    
  


    

How to Search in Tables

The filter filter is used in conjunction with ng-repeat to filter items based on the search input. This can be applied directly to the ng-repeat as shown in the example above.

Conclusion

In this article, we explored how to create and manipulate tables using AngularJS. We covered various functionalities such as displaying data, sorting, pagination, and implementing a search feature. Understanding these concepts is essential for working with data in Angular applications.
